' Y Gas BURNER.

`Application filed .Tune 1,

The invention relates to improvements in gas burners designed primarilyfor consuming natural gas, and the principal object of theinvention. isVto provide axburner of this type which is extremely simple andinexpensive, yet will be ellicient and reliable Y andwill insure properymixture' of air and gas to attain the best results.

One of the most important uses of the burner is in connection withboilers and by proper installation, I have been enabled to overcome thediflicultiesv heretofore'prevalent, due to baking of the mud in the mudrings of boilers, which condition is the cause ofat least seventy-fiveper cent 'of the boiler trouble commonly encountered when gas or naturalgas is used as fuel.

,Vitli the foregoing in View, the invention resides in the novel subjectmatter hereinafter described and claimed, the description beingsupplemented by the accompany'- ing drawing.

Figures 1 and 2 are respectively a side elevation and a top plan View ofa burner constructed in accordance with the invention.

Figure 3 is a longitudinal sectional view on line 3=3 of Fig. 2.

Figure 4 is an end elevation.

Figure 5 is a transverse section on line 5-5 of Fig. 3.

Figure 6 is a fragmentary plan view showing the preferred manner ofconnecting two of the burners for use with a-boiler.

The drawings above briefly described may be considered as the preferredform of construction, with the understanding however 'that within thescope of the invention as claimed, numerous variations may be made.

The numeral 7 designates an elongated burner body of trough-like form,the bottom of this body being designated at8, while 9 refers to itscontinuous upstanding side wall. At longitudinally spacedpoints, thebottom 8 is provided with inlet openings 10 for gas and air, and theseopenings are preferably surrounded by upstanding nipples 11. Bypreference,the bottom, side walls and nipples of the body 7 are all castas a single unit.

Disposed at the open top of the body 7, preferably within the upperportion of the side wall 9, is a baille 12, said baffle being spacedfrom said wall to provide a narrow outlet 13 for the mixture of gas andair. This baile 12 is preferably in the form of a 192e. serial No'.V113,092.

Hat cast plate, and in the preferred form of construction, is providedwith'downwardly.

projecting longitudinal flanges 14 kwhich are inwardly spaced from thewall Qand in the present showing have downwardly' projectingleg portions15 whiclifrest upon the Abotvtoni 8. The flanges 14 co-operatewith theplate 12 in checking the discharge of gas and air through the outlet 13and consequently insure thorough mixing and heating of suchV gas and airbefore they are discharged for combustion.

Disposed longitudinally under the burner body 7, is a gas supply pipe 16having outlet orices' 17 in line withthe openings 10 and nipples 11. Thegas is of course discharged under pressure from the orifices 17 and asit passes throughthe openings 10 and nipples 11, it induces air to enterthrough said openings -and nipples, and the gas and air become thoroughlmixed under the baille-12 before they areV ischarged, as aboveexplained.

In order to get the proper mixture of air and gas, it is necessary toconsider climatic conditions and altitude, and in order that the burnermay be successfully used under any conditions which may be encountered,I

provide for adjusting the pipe 16 toward and from the body 7 and byso-doing, I am enabled tofvary the amount of air entering the burnerbody, as occasion may dictate.

Preferably, pairs of arms 18 are secured by bolts or the like 19 to thebody 7, said arms projecting downwardly from said body and engagingopposite sides of the pipe 16. These arms are provided with longitudinalslots 20, and bolts 21 pass through said slots over and under the pipe1'6. This arrangement permits the necessary adjustment of the pipe andafter such adjustment, tightening of the bolts lwill effectively clampit and the burner body in fixed relation. The arms of each pair may ifvdesired be bent from a single metal bar, as will be clear from Figs. 4and 5.

I preferably use the burners in groups of two, as indicated in Fig. 6,and when so doing, the pipes 16 of the two burners may be connected withaV common supply pipe 22 by means of appropriate piping and connections23.

Excellent results are obtainable from the details disclosed and they aretherefore preferably followed. However, as above stated, variations maybe made within the scope of the invention as claimed.
